So, the LCM of 25, 33 is 825.
Least Common Multiple (LCM) of 25 and 33 with the help of Prime Factorisation
One method for determining the LCM of 25 and 33 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:
Here is 25's prime factorization:
| 5 | 25 |
| 5 | 5 |
| 1 |
Prime factors of 25 are 5.
25 = 52
And this is 33's prime factorization:
| 3 | 33 |
| 11 | 11 |
| 1 |
Prime factors of 33 are 3,11.
33 = 31×111
When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered:5, 3,11
.31×52×111 = 825
This shows that the LCM of 25 and 33 is 825.
How to Calculate the LCM of 25 and 33 Using Common Multiples
The first step in determining the Least Common Multiple of 25 and 33 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 25 and 33:
Lets look at the first ten multiples of these numbers, 25 and 33:
25,50,75,100,125,150,175,200,225,425 are the first ten multiples of 25.
33,66,99,132,165,198,231,264,297,561 are the first ten multiples of 33.
You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 25 and 33, for example, are 300, 425, and 528. 825 is the least common multiple since it is the smallest.
25 and 33 have an LCM of 825.
Least Common Multiple of 25 and 33 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 25 and 33, than apply into the LCM equation.
GCF(25,33) = 1
LCM(25,33) = ( 25 × 33) / 1
LCM(25,33) = 825 / 1
LCM(25,33) = 825
